in lrry ooee '1. In a typewriting machine having a framework and a carriage, the combination with a margin gage on the framework of a lever on the carriage, main and auxiliary silences the main-stop and brings the aux- 1 iliary stop 18 into use. Since said auxiliary I stop 18 is located aconsiderable distance to the right of the main stop 5, it can cooperate 5 with the gage 6 while the carriage is at the stops on the lever, the auxiliary stop norleft-hand portion of its travel, thereby mamally held in idle position by the lever terially increasing the possible width of the I which is shiftable to reverse the operative left hand margin on the sheet. For exrelationship of the main and auxiliary stops ample, the distance between the stops 5 and 1 relative to the gage to effect a variation'in 10 18 may be nearly equal to one-half of the the width of the margin on the sheet.

2. In a typewriting machine having a framework and a carriage, the combination with a margin gageon the framework, of a lever on the carriage, main and auxiliary the auxiliary stop 18, together with the gage 6, would effect the arrest of the carrange of travel'of the carriage, and hence f riage at any point in the first half of the rel 15' turn travel thereof, whereas, the main stop stops on the lever, the auxiliary stop nor- 5 would be capable of arresting the carriage mally mild in idle position. by the l v r 7 only at any point in the latter half ofsuch which is shiftable to ieveise the operative return travel. The rocking of the lever 3 to relationship of the main and auxiliai y sto s bring the auxiliary stop 18 into effective porelative to the gage to effect a variation in 20 sition relative to the margin gage 6, throws I the width of the margin on the sheet, and the main stop 5 to ineffective position, as 1 locking means for holding the lever in shiftshown in Figs. 1 and 4.
